10 Best API Testing Tools to Use in 2023 — (SOAP and REST Tools)
API testing has become a must with the rise of cloud applications and connected platforms. Many of the services we use every day depend on multiple APIs that work together. If even one of them stops working, the whole service is at risk. API tests are now required for software developers to ensure that APIs work as expected.
There are a lot of API testing tools on the market today, so how do you choose the best one? Don’t worry; we’ve compiled a list of the best API testing tools to make your work go faster. Before we look at the top 10 API Testing Tools in 2023, let’s go over the basics of API testing.
What Should You Know About the API?
An API is an Application Programming Interface, a piece of code that makes it easy for two software programs to talk to each other and share data. APIs are a crucial part of the software development lifecycle (SDL). They let software applications, like Shipping API Integration, talk to each other and other services. APIs are essential to the software development life cycle because they let software programs talk to each other and other services.
Most of the time, APIs let software programs talk to other services like databases or web services. The service provider sends the request when a user asks an API for information. The service provider then responds, which is sent back to the user. The best way to think about an API is as a set of instructions that let two programs or applications talk to each other.
The other common way APIs are used in mobile app testing is when they let two programs or apps talk to each other. When a user asks an API for information, the request goes to the service provider. The service provider then makes a result, which the API sends back to the user.

Best Tools for Testing API (SOAP And REST API Test Tools)
1. Postman
Developers, testers, and project managers use Postman, one of the world’s most popular API testing tools. It is used to test APIs and services that work with APIs, send and receive HTTP requests, make and send HTTP POST requests, and do much more.
You can send HTTP requests to web services through the Postman API and get JSON responses back. It has robust testing and monitoring tools, and you can make powerful API test suites by combining Postman API testing with Katalon Studio testing.
What’s Important
- Makes it possible to do Boolean tests without a command line.
- Postman’s interface can be used to get API data.
- Comes with tools for automating tests, debugging, monitoring API, running requests, and managing workspaces.
- A REST client that is easy to use.
2. GetAPI
ReadyAPI Price: SoapUI (starts at $659 per year), LoadUI Pro (starts at $5999 per year), ServiceVPro (starts at $1199 per year), and ReadyAPI (custom pricing) are the different ways to pay for ReadyAPI. Get a quote). The ReadyAPI is free to try for 14 days.
SmartBear offers the ReadyAPI platform for testing RESTful, GraphQL, SOAP, and other web services for functionality, security, and load.
You get four powerful tools in one easy-to-use platform: API security testing, API functional testing, API performance testing, and API and Web virtualization. This platform will help you make sure that all web services are good from start to finish.
It gives you various automated ways to add API testing to your CD/CI pipeline during every build. You will be able to make API tests that are complete and based on data.
Features:
- You can add ReadyAPI to any environment.
- It has a Smart Assertion feature that lets you quickly create assertions for a large number of endpoints.
It works with Jenkins, Git, Azure, Docker, etc., right out of the box.
- It also works with the command line to help automate testing.
- It lets functional tests run in parallel and enables jobs to wait in a queue.
- It has functions and features that let you reuse functional tests and create real-world load scenarios.
- ReadyAPI also has ways to eliminate dependencies while testing and building.
3. Katalon
Katalon is one of the best API load testing tools. It makes it easy for people who don’t know how to code to run API tests without a lot of trouble. This tool can be used on the web, on your computer, and your phone.
Katalon is becoming one of the best API testing tools for 2021 because it has a simple user interface and accessible API services for developers and testers.
What’s important:
- It works with SOAP requests, SSL client certificates, and REST.
- API test data can be set up with UI testing
- Your tests can be easily imported from Swagger, WSDL, Postman, and WADL.
- It works with AsserJ, so you can easily make a BDD-style assertion.
- Gives more reliable tests and better test coverage
- It helps teams work together better because test report dashboards are helpful.
4. ACCELQ
ACCEL is the only cloud-based platform for continuous testing that automates API and web testing without writing a single line of code. IT teams of all sizes use ACCELQ to speed testing by automating critical lifecycle parts, such as test design, planning, generation, and execution.
